How do i wire 2 amps together


Good morning Audiophiles. I NEED HELP! So i am trying to set up set up a Home Theatre and i think i may need a second stereo amp to drive my centres, but i want to connect with people who have this set up to explain to me how this can be done. This is my scenario: I have the Onkyo TXNR-1030 (9.2 channel). I have a Boston Acoustic (BA) VR Centre, 2 X BA VR3 Reference floor standers, 2 X Pioneer SRS88TB side surrounds, 2 X BA VR3 Reference Dipoles at the back, 2 X Onkyo Atmos for front heights and in the ceiling a pair of Yamaha NS-CI800. Subs are BA PV800, and Yamaha YST-SW320. I also have a KEF Centre T301C (for Netflix etc.). So i want to have a 7.2.4 set up as this would work in my space. Now the AV Receiver only drives 11 channels (at 75W RMS, 8 Ohm), and rather than driving my Atmos speakers, i was wondering if it were possible/how to drive perhaps my centres and the Centre KEF with a 2nd stereo amp? How are the two amps connected to synchronise? Is this a master/slave scenario? Your advice, as well as links to how this can be done would help. Am finding forums online but nothing that drills down to basic level of how this is wired to be done. I am no techie, and a beginner in this space so i would appreciate the dumbing down approach. Thank you for your advice...

Hello gajadhar,

     The proper method to do what you want is to use the pre-out connections on the back of your Onkyo receiver.  These output 'line-level' audio signals that have not yet been amplified
     There are pre-outs for each of the channels on you receiver.  Just choose the channel/speakers you want to drive with an external amp and then use regular rca type audio cables to connect from the pre-outs to the inputs on the amp you buy.  Then connect your speaker(s) to the back of your new external amp(s).
     It's your choice on whether you want to use a few mono or stereo external amps or a single multi-channel amp.  Using separate mono amps will technically provide the best channel separation but a single multi-channel amp would be the least expensive and probably the most convenient.

Hope this helps a bit,
    Tim

okay, you're posts are actually very confusing.  At first, it seems that you want advice on how to power two completely different center channel speakers at the same time:

- Boston Acoustic VR Center

- KEF Centre T301C


If this is what your asking, then my answer is this is not recommended.  You should only have one center channel speaker and it should match your left/right speakers as closely as possible.  So, you should continue to use your BA VR Center speaker.  The KEF T301C should not be used in this system.

If you have a different question, maybe you should ask that specifically.  Your second post indicated you might be asking about a "hybrid" system.  If so, please do some forum searches on that.

Ok, clearly my language is all wrong! I received advice on another forum and was told what i am going on about is the pre-amp with HT bypass, and power amp set up that is needed to listen to pure stereo on my system. Any advice on what to get and how to wire would be appreciated. Note, i have a very limited budget of about 600USD
